Function graphiql_filter

pub fn graphiql_filter(
    graphql_endpoint_url: &'static str,
    subscriptions_endpoint: Option<&'static str>,
) -> BoxedFilter<(Response<Vec<u8>>,)>

Create a filter that replies with an HTML page containing GraphiQL. This does not handle routing, so you can mount it on any endpoint.

For example:

let graphiql_route = warp::path("graphiql").and(graphiql_filter("/graphql",
None));

Or with subscriptions support, provide the subscriptions endpoint URL:

let graphiql_route = warp::path("graphiql").and(graphiql_filter("/graphql",
Some("ws://localhost:8080/subscriptions")));
